    Default How to call table?

    Hello!

    I would like to call the table "TablePrintDemo"(se below) from another class and method.
    I also would like to pass a matris with values to be printed in the table.

    What method should I call in the class TablePrintDemo ?

    TablePrintDemo is downloaded from:

    Using Swing Components: Examples (The Java™ Tutorials > Creating a GUI with Swing > Using Swing Components)

    Hope I can get some help with this
